To @H who/m, t may concern:

Be it known that l, MICHAEL MARINO, a citizen ot the `United States,residing` in the borough of Brooklyn, city ot New York, county ot Kings,and State of New York, have invented certain new and useful Tmprovementsin Valves for Tater-Closets, ot which the following is a specilieation.

My invention relates to valves for etfecting and controlling theflushing of water closets, and particularly to those actuated by thedepression of the water closet seat.

The object is to avoid the use of complicated valves and apparatus, andto afford simple and cheap as well as effective and durable means foraccomplishing the desired result; and the invention consists in thespecific construction and arrangement of parts hereinafter set forth.

,ln the accompanying drawings; Figure l, is a top view of duplex valvemechanism made in accordance with my invention; Fig. f., a t'rontelevation thereof; Fig. 3, a rear elevation thereof; Fig. ll, a centrallongitudinal section taken upon plane ot' line #4, Fig. 2, except thatin this case the inlet valve is represented as open and the dischargevalve as closed; Fig. 5, is a diagrammatic view illustrating thepractical use of my duplex flushing valve.

C, represents a valve casing in which two conical plug cocks or valvesi), fv, are seated, said casing C, being formed with a central standardo, and base c', for securing it in position. Intermediate as related tovalve seats, the casing C, is formed with a lateral branch c2, threadedexternally for engagement with a pipe coupling 03, by which the tankpipe t, is connected with the passage between the valves c, c,-said pipeopening into the bottom of the sealed tank T, and constitutingessentially a stand pipe.

I, is the inlet or supply pipe connected to one end of the casing C, bythe pipe coupling i', and D, the discharge or flush pipe connected tothe other end of the casing C, by the coupling d, and communicating withthe upper part of the closet basin B.

The conical valve plug o, which controls the inlet is provided with alever arm o, and the conical valve plug e, which controls the dischargeis provided with a lever arm i12-these two lever arms being pivotallyconnected by means of a link Z. The valve plugs c, and QJ, are so timedwith relation to each other that one is open when the the other isclosed, and they are held in their normal positions with the inlet valveo, closed and the discharge valve v, open, by retractile means, such forinstance as a spring r, interposed between the lever arm c, and a studor post c4, on the casing C. The lever arm c, of the inlet valve o, isformed with an extension om, on the other side of the valve plugconstituting the operating arm, and this operating arm om, is connectedby a wire w, or other flexible means, with a rear extension s, ot' thewater closet seat S,one or more guiding pulleys g, being used to directand hold the flexible connection fw, taut. The rear extension s, of theseat S, constitutes the short arm of the lever of which the seat is thelong arm, f, being the ulcrum, and t-he short arm or extension s, beingmade sutticiently heavy to act as a counterweight to the seat S, so thatwhen the latter is not forcibly depressed the seat is held normally openby said counterweighted short arm or extension s, as shown in Fig. 5.

Then the seat is depressed the flexible connection fw, acting on theoperating arm om, of the inlet valve plug against the resistance of theretractile spring r, opens the inlet valve o, and closes the dischargevalve lU. As a result the water flows upward through the pipe t, to thesealed tank T, in a manner well known in the art, affording a suitablesupply :tor the flushing of the closet bowl B, when the seat S, isreleased. As the seat resumes its normal, raised, position, owing to theaction of the counterweight s, the retractile means r, returns the valvearms o, and fox, to their normal positions, closing the inlet valve '0,and opening the discharge valve fu, under which condition the waterflows from the tank T, through the stand pipe 15, valve o', and flushpipe D, into the bowl B, from which it passes to the waste pipe E," thestand pipe t, valve casing C, and lflush pipe D, being tinally drainedafter the flush by a drain conduit cl, interposed between the casing C,and the waste pipe E, as is customary in similar cases.

The usual stops L, (Fig. 2) on the valve plugs o, o', cont-acting withshoulders on the casing, limit the motion of the said valves in eitherdirection.

By my construction and arrangement of parts complicated 'valve mechanismand washers are dispensed with, and cheap, simple and durable partssubstituted which are not liable to get out of order or need repair,-theretractile spring being the only part needing renewal until the valveplugs are actually worn out by long service. Furthermore the operationis comparatively easy because there is but slight resistance to beovercome; and the parts are all outside and conveniently accessible.

TWhat I claim as my invention and desire to secure by Letters Patent is,

A valve casing, a plurality of rotatable valves mounted in said casingin alinement with each other and intermediate the inlet and outlet tosaid casing, a connection for a tank, said connection being interposedbetween said valves, an arm connected with one of said valves, anoperating arm connected with the other valve and extending in oppositedirections from its connection with the valve in a straight line andsubstantially parallel with the first-named arm, a link connecting theadjacent ends of said arms, a spring connected at one end to theoperating valve arm between its connection with the valve and the linkand extended parallel with the casing and having its other end attachedadjacent the end of the casing opposite the valve to which the operatingarm is connected, and a flexible ligament connected with the other endof said operating arm for connection with an operating device andextending substantially parallel with said link and a support exteriorof and' supported by the casing and carrying a support for saidligament.
